Do I have a Sink Leak?

Drip. Drip. Drip drip drip. Drip. We’ve all heard it at some point in our homes and offices. It’s the Edgar Allen Poe Beating Heart of the plumbing world: a sink leak. Before going crazy from the drips, take action. There are certain things you can look for before you call for professional help! First, determine the source of the leak. You will not be able to repair your plumbing fixtures if you are unable to find the source of the problem. If the leak is big, you may be faced with a water puddle, and if the leak is minor, you may simply find a damp wall or cabinet in front of you. Either way, understanding the problem is the first step towards resolving it. A sink leak can be caused by a wide variety of reasons. There are two questions to ask: Is the leak coming from the main water supply or from your own drain?

Sink Leak from the Main Water Supply

As water is supplied to your faucets, it is under a lot of pressure, and this pressure can not only cause the hoses underneath to leak or drip due to a change in position, but may also cause them to burst. However, a leak in the hose is easily to fix, as most water supply hoses are removable and flexible and can be installed with ease. The main supply system also includes a number of valves and pipe joints, which may leak if they are not fitted properly. You can tighten the pipes connections and valves using a wrench. However, if the pipe is leaking due to a crack or breakage, it is best to replace it so that you will not have to face a costly repair later on. If you are unable to tighten the loose joints with a wrench, you can use adjustable pliers as well.

Sink Leak in Your Drain

This is where things get a bit more complicated. Most kitchen sinks have a P-trap located underneath, which may leak if it is fitted improperly. Alternatively, a blockage in the drainpipes below it may also cause the trap to fill with water, resulting in a leakage.

The trap is easy to remove in case of a leak. Once you have unscrewed and disconnected it from the fittings, you can tighten the screws of it and clean it thoroughly to ensure that all of the debris collected inside is removed. Once the trap is clean, you can attach it back into place, and if it has rusted or corroded over time, you should opt for a trap replacement.

This is also the best time to clean your drainpipe if you suspect a clog. You can use a metal wire to prod the clogged drain and remove the debris that has collected in the pipes to ensure a smooth flowing drain once more. As soon as the drain is clean and functional, the trap will work perfectly and the leak will be resolved. The following are some other common causes of sink leaks in your home:

  • Sink Leak from the Combination Trap

The sink combination trap is the drain piping used underneath the sink. Within this plumbing fixture, any of the joints may be loose, which could be causing the leakage. These joints can be tightened with the help of a wrench, and steel clips can be added instead of plastic clips to keep the fittings in place. Alternatively, you can also change the entire fitting underneath your sink to avoid the leakage in future.

  • Sink Leak from Valve Leaks

It is possible that your sink leak is occurring due to a leak in the angle valve or shut off valve located underneath the sink. However, not all of these valves are located in direct sight and may be placed within the wall. In such a scenario, you may need to break down a portion of the wall in order to reach the vale and replace or repair the valve as needed.

  • Sink Leak from a Leaking Hose

Most sinks have removable and flexible hoses underneath that connect the piping to the faucets. These hoses may start leaking due to damage, but they can easily be replaced. However, if your hoses are not easily removable, you will need to replace the entire fixture fitting of the sink.

  • Sink Leak from the Waste Pipe

If your sink leak is resulting in a water puddle being formed on the floor or within your cupboard, you may be facing a waste pipe leak. The waste pipe, however, is usually located within the wall and in order to replace it, you will need to break the wall and install a new pipe instead. Waste pipe leaks are usually caused when the drain becomes clogged with dirt and debris, leading to an ineffective drainage system.

  • Sink Leak from Eroding Silicon

Silicon is the material that is used to seal the sink in place on top of your counter or cupboard. Once the sink has been placed within the space that is designated for the sink, the edges of the sink are filled with silicon to ensure that the fitting is watertight. Hence, water cannot drip down into your cupboard if the silicon is in place. Unfortunately, silicon may erode over time, and this is when you need to replace the filling on the edges of your sink so that the water on your counter does not drain down into your cupboard through the edges of the sink.
